// Executes an openCypher query. See Accessing the Neptune Graph with openCypher (https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-opencypher.html)
// for more information. Neptune supports building graph applications using
// openCypher, which is currently one of the most popular query languages among
// developers working with graph databases. Developers, business analysts, and data
// scientists like openCypher's declarative, SQL-inspired syntax because it
// provides a familiar structure in which to querying property graphs. The
// openCypher language was originally developed by Neo4j, then open-sourced in 2015
// and contributed to the openCypher project (https://opencypher.org/) under an
// Apache 2 open-source license. Note that when invoking this operation in a
// Neptune cluster that has IAM authentication enabled, the IAM user or role making
// the request must have a policy attached that allows one of the following IAM
// actions in that cluster, depending on the query:
//   - neptune-db:ReadDataViaQuery (https://docs.aws.amazon.com/neptune/latest/userguide/iam-dp-actions.html#readdataviaquery)
//   - neptune-db:WriteDataViaQuery (https://docs.aws.amazon.com/neptune/latest/userguide/iam-dp-actions.html#writedataviaquery)
//   - neptune-db:DeleteDataViaQuery (https://docs.aws.amazon.com/neptune/latest/userguide/iam-dp-actions.html#deletedataviaquery)
//
// Note also that the neptune-db:QueryLanguage:OpenCypher (https://docs.aws.amazon.com/neptune/latest/userguide/iam-data-condition-keys.html#iam-neptune-condition-keys)
// IAM condition key can be used in the policy document to restrict the use of
// openCypher queries (see Condition keys available in Neptune IAM data-access
// policy statements (https://docs.aws.amazon.com/neptune/latest/userguide/iam-data-condition-keys.html)
